PHP如何舍入总计

Question

我很困惑在PHP中使用round函数，我在我的系统中使用PHP制作了一些计算函数，但答案仍然没有四舍五入。

我希望所有总计将在 percent_complete 中进行舍入。

有人可以帮我修复此代码吗？这是原始代码..

<?php echo $row_sr1['percent_complete'] = ($row_sr1['partial_complete'] + $row_sr1['full_complete']) / $row_sr1['appt_today'] * 100;?>

，这是我尝试舍入但不成功的代码。

<?php echo round($row_sr1['percent_complete']),2 = ($row_sr1['partial_complete'] + $row_sr1['full_complete']) / $row_sr1['appt_today'] * 100;?>

Answer 1

你的回合功能在错误的位置。

<?php
  echo $row_sr1['percent_complete'] =
         round(
           ($row_sr1['partial_complete'] + $row_sr1['full_complete']) /
             $row_sr1['appt_today'] * 100,
           2);
?>
